For now, Ethereum remain the King of the Altcoins and what is surprising is that with all the funding that all these Ethereum killers received including the all these L2s that are receiving attention now, Ethereum is still far ahead, I think Binance chain is the closest to Ethereum, but it has not being able to sustain the growth or catch up
Binance chain is just copy of Ethereum chain.. The popularity of BSC chain is due to Binance exchange.. People trust BSC chain and number of partnership of big projects are because of high demand of community. Bsc chain is good to save fee but there is no project still launched which will be competitive of the Ethereum..
Bsc chain is also popular due to its low charging fee and how some projects are built under its Blockchain. The authentication of ETH over BSc arise due to much fake projects built under BSc. Most investors highly trust projects built on ETH Blockchain to that of BSc. This has given ETH more upper hand than BSc in the crypto space.
